ALFRED FORNANDER, OF NEWV YORK, N. Y., ASSIGNOR TO THE CARPET YARN PRINTING COMPANY, A CORPORATION OF NEWV YORK.

MECHANISM FOR PROPELLING COLOR-CARRIAGES.

SPECIFICATION forming part of Letters Patent No. 737,917, dated September 1, 1903.

Application filed August 8, 1902. Serial No. 118.849. (No model.)

T0 to whom, it may concern:

Be it known that I, ALFRED FORNANDER, a subject of the King of Sweden and Norway,

residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Mechanism for Propelling Color-Carriages, of which the following is a specification.

My invention refers to improvements in yarn-printing appliances, and more particularly to mechanism for moving the color-carriage along and underneath a yarn-drum for the purpose of printing longitudinal stripes of color on the yarn wound on said drum by means of appliances mounted on said colorcarriage.

The objects of my invention are to provide means for propelling the color-carriage along the yarn-drum in such manner as to insure a reliable and rapid movement of the same along the drum and to provide ready means for reversing the direction of its movement,

all free from jarring and jolting and without lost motion and at a comparatively slight expense of power.

I accomplish these and other useful objects by the means hereinafter specified, and set forth more particularly in the claims.

In the accompanying drawings, forming part of this specification, and wherein like reference-numbers refer to corresponding parts, Figure 1 is a side elevation, and Fig. 2 a ground plan, partly in section, of a yarnprinting apparatus constructed according to my invention, the yarn-drum being, however, omitted in Fig. 2, while Figs. 3 and 1 illustrate, on a larger scale, a set of lazy-tongs with proper connections employed in my improved apparatus, Fig. 3 being a side elevation and Fig. 4 a ground plan.

In said drawings, 10 is the yarn-drum, supported in any suitable manner, around which a layer of yarn 11 is Wound. For the purpose of printing the yarn there is generally employed in that class of machines a printing mechanism comprising a color-box, as 12, containing coloring material, and a printingwheel 18, rotating therein and removably mounted upon a carriage 14. This carriage is made to travel forward and backward along two rails, as 15, forming atrack 16, and so as to force the printing-wheel against and hold it in contact with the yarn along the under side of the drum during such travel, thereby producing ridges of color along the yarn on the drum subsequent to proper partial revolutions of said drum.

As my invention refers altogether to the.

means for so propelling the color-carriage along said track, I will not give a detail description of the printing apparatus itself.

My improved means for propelling the carriage comprise the following parts:

17 is a double standard or support placed on one side of track 16 and preferably opposite the circumference of said drum and approximately opposite the central portion of its length. Said standard carries a shaft 18,

upon which a set of lazy-tongs 19 is pivotallymounted. The joint 20, which is the central joint of said lazy-tongs farthest removed from shaft 18, is extended by means of arod 21, reaching to and beyond the central plane of track 16, and said rod connects with carriage 14 by means of a sleeve 22, attached to the latter, in which sleeve it is inserted and within which it is capable of sliding. The lazy-tongs are adapted to play lengthwise with reference to the drum to a sufficient extent to withdraw the color-carriage at the ends of the drum entirely from underneath the same, so as to permit of lifting off a color-box and substituting another one in its place. Such movement is produced and its extent is regulated by means of the mechan-- ism illustrated more particularly in Fig. 1, wherein 23 is a gearwheel mounted on a shaft 24 and receiving movement from any suitable motor. It carries a crank-pin 25, from which extends a connecting-rod 26 to a lever 27, fixedly mounted upon a shaft 28, which has its hearings in a double standard 29. Another lever 30, also fixedly mounted on shaft 28, and which thus, together with lever 27, forms an elbow-lever, is connected by means of a set of connecting-rods 31 with joint 32, which is the central joint-on the lazy-tongs nearest to shaft 18. While I do not intend to confine myself to the 'particular means described for transmitting power from a shaft, as 24, to the color-carriage, I prefer to employ the same, as therebya very simple mechanism is provided for actuating and reversing the lazy-tongs and for imparting to the carriage a substantially uniform movement while it is traveling along the yarn-drum.

In pivotally connecting rod 31 with joint 32, which is the central joint nearest to shaft 18, I am enabled to convert comparatively slight movements of the device for transmitting power. from shaft 24 to joint 32 into much more extensive movements of the color-carriage. It will be observed that as the lazy-tongs are placed on one side of the color-carriage and close to the floor the same will not in any way interfere with the proper manipulation of the color-tank and color-wheel mounted thereon. It sometimes happens that during the printing operation the color-carriage jumps the track 16. This in most cases will be due to the partial swinging or turning of the yarn-drum while the color-wheel is in engagement with the under side of the drum. If the lazy-tongs and color carriage were connected by means of an ordinary pin-joint, such lateral displacement of the carriage would be apt to result in bending or breaking of the lazy-tongs. To guard against this, I provide an ordinary slip-joint between rod 21, extending from the lazy-tongs and sleeve 22 on the carriage, so that in case the carriage should jump the track in the di rection away from standard 17 said sleeve would simply slide from contact with said rod, and any injury to the lazy-tongs resulting from such displacement of the carriage would thus be guarded against. As the yarn-drum during successive trips of the color-carriage is always swung in one direction only, it will be seen that it is principally necessary to provide for such separation of the carriage from the lazy-tongs in one direction, and this is ac-. complished by placing standard 17 on that side of track 16 from which the under side of the drum swings toward the center of said track. If, however, the carriage should leave the track in the direction toward standard 17, sleeve 22 could then slide along rod 21, and injury of the lazytongues would thus be avoided.

I do not wish to confine myself to the details and detail combinations herein set forth, as it will be seen that they might be varied materially without departing from the spirit of my invention. Thus instead of placing the lazy-tongs on one side of the. track they might be placed between the rails forming the same, and, besides, the shaft 18 instead of being located opposite the circumference of the drum might be placed beyond the length of said drum. Rod 21 instead of forming an extension of one of the joints of the lazy-tongs might be connected with any other part of the same.

I claim 1. The combination with a yarn-drum and a color-carriage adapted to move longitudinally with reference to said drum, of a suitable stationary support mounted substantially opposite the circumferential surface of the drum, and means attached to said support for propelling the color-carriage along the drum between said support and opposite ends of the drum.

2. The combination with a yarn-drum, a track, and a color-carriage adapted to move longitudinally with reference to said drum, of a suitable support mounted substantially opposite the central portion of the drum and outside of said track, and means attached to said support and to the carriage for propelling the latter along the track on opposite sides of said support.

3. The combination with a yarn-drum, and a color-carriage adapted to move longitudinally with reference to said drum, of a pivot, lazy-tongs mounted upon said pivot and attached to the carriage, and means for expanding and contracting said lazy-tongs on both sides of said pivot.

4. The combination with a yarn-drum, a pair of rails forming a track, and a color-carriage adapted to move thereon longitudinally with reference to said drum, of lazy-tongs pivotally mounted on one side of the track, a connection extending from said lazy-tongs to a portion of the carriage between said rails, and means for actuating said lazy-tongs.

5. The combination with a yarn-drum, a

track, and a color-carriage adapted to move thereon longitudinally, of a pivot placed opposite the drum, lazy-tongs mounted thereon and connected with the carriage, and means extending beyond the length of thedrum for actuating said lazy-tongs.

6. The combination with a yarn-drum, a track, and a color-carriage adapted to move thereon, of lazy-tongs, a joint being formed between the same and the color carriage adapted to become separated upon lateral displacement of the carriage.

7. The combination with a yarn-drum, a track, and a'color-carriage adapted to move thereon, of lazy-tongs placed on one side of said track, and a projection thereon extending into a suitable sleeve on the carriage and adapted to slide therein.

8. The combination with a yarn-drum, a track, and a color-carriage adapted to move thereon, of mechanism for propelling said carriage along the track, and a connecting device between said propelling means and said carriage adapted to become separated upon lateral displacement of the carriage.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 7th day of August, 1902.
